Description
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
Implement a Spark SQL `rlike`, which checks for specific fast paths in order to avoid using a regex. These types of fast paths are currently implemented for `like`.
**Describe the solution you'd like**
Implement `rlike` functions, similar to the `like` functions. Given the existing code this should be limited to a few functions, with the remaining generated through macros.
**Describe alternatives you've considered**
**Additional context**
Contributor guide
Research direction
Start by locating the existing `like` functions and their macros, then trace the entry points for Spark SQL string expressions. Implement the corresponding `rlike` functions with the requested fast paths and verify the relevant expression tests; the issue names no file or test, so repository search is the first step.
